This technique is divided in three, precise movements, that must be performed when the target is in the right range of three steps (三歩の間合い, Sanpo no Maai). First, there's the "Start" (序, Jo), where the user starts falling forward, and using that momentum moves diagonally towards the opponent, ready to spring, in order to catch his attention. When the enemy tries to attack, the "Crossing" (交, Ko) follows, as the user crosses their legs to create an unbalanced stance and using the momentum quickly falls sideways, out of the enemy's sight, apparently disappearing. Then before the enemy can react, the user finally cuts him to the flank (斬, Zan) with a powerful slash, finishing him off before he can realize what happened.
Gama has also developed a personal variation of the technique shown during his duel against Muraku Matsumoto: since his opponent already knew about the crossing, he executed it twice in a row (first to left, then to right) so that he could attack him using Kosen instead of the slash to finish him off.
